UNITED STATES PATENT OFFICE NOZZLE LOCK Homer D'. Moser, Fort Wayne, Ind., assignor to The Wayne Pump: Company, Fort' Wayne, Ind.; a corporation of Maryland Application May 19, 1951,` Serial No.1227,265

1 Claim. 1. This invention relates to a new and improved nozzle locky and more particulariy toa lock for retaining nozzles of gasoline dispensing systems for` unauthorized removal from the` dispensing' housing or casing.

lnV usual types of dispensing pumps` for gasoline orsimilar liquids it is customary to provide a dispensing hose withI a metal nozzle thereon. This nozzle contains a manually operable shut ofi valve andV may contain other control unit-s. The hose leads fromy the housing whichY contains' the pump, together with the meter and counter ory computer units. This' housing is provided with arecess which serves as a receptacleV for' an exposed padlock to prevent.unauthorizedV re moval from its housing. If the main control switches are on, the dispensing apparatus may be operated to deliver liquid by operation of the nozzle controls when the nozzle is removed from the housing and from engagement with the nozzle switch plate so that in the absence of an attendant, it would be possible for an unauthorized person to secure a delivery of liquid. Even when the main switches are opened, as when a station is closed for the night, it is highly undesirable to permit unauthorized persons to remove a nozzle from its housing. The nozzle and hose may be stolen or intentionally damaged or may be left where it may be dam aged or be a hazard to traffic.

It is an object of the present invention to provide a new and improved nozzle lock for dispensing equipment.

It is a further object to provide such a lock which positively retains the nozzle in its normal storage or non-use position.

It is also an object to provide a nozzle lock which is operable only from the inside of a dispensing housing and hence only by the possessor of a key to the housing.

It is an additional object to provide such a lock which is simple in design and operation and designed for commercial production and use.

Other and further objects will appear as the description proceeds.

the construction of'Figure l also partly in seetion; andy Figure 3` is" a horizontal' transverse section'.

through the constructions of Figures 1- andi 2,5

In the drawings", a dispensing housing II` is' shown as` having' a nozzle receptacle i3' secured'l thereto. This receptace I3 comprises a lower' recess I5 and an upperv pocket I't into which the upper end le' of tne'nozzie 21 is. tte'd. `Tidei particular construction of the nozzle 2l.' forms no part of' the present invention, but the nozzle is provided with the usual. guardi' member 2'3" and valve operating lever 25',y as.. shown in broken lines in Figurev 2.

The nozzle hook. 2T'is' secured in the lower portion of the' receptacle I3 by means of the bolt 28 and nut'. 3l); This nozzle hook- L. as best shown inL Figure 2, is. providedwitha perforation 32 forth'e reception of' the locking-pin 3.4'. The nozzle'switch lever 36 is pivoted on member 385 which is held' iri4 place by nut-4U in the! rear wall` of the nozzle receptacle I3. As shown. in

Figure 3, thel lower portion 4'2' of the nozzle lever- ."I'IiV is bifurcated so that it' extends down" on either side of the nozzle hook 2l. The nozzle lever 36 has the rod 44 pivotally connected thereto, this rod extending through the rear wall of the nozzle receptacle I3. It will be understood that this rod 44 is connected to the usual type of interlock mechanism and particularly to the switch for controlling the pump motor of the dispensing apparatus. This particular construction is well known in the art and will not be described in detail since it forms no part of the present invention.

The lateral wall 5I) of the nozzle receptacle I3 is thickened in the form of a conical boss at 52 in order to give greater support to the locking pin 34. This locking pin has an enlarged head 54 and the compression spring 56 which is fitted around the pin 34 bears against the underside of head 54 and against the outer face of the side wall 5U of the receptacle I3 so that it normally urges the pin 34 outwardly of the receptacle and holds it in the unlocked position, as shown in Figures 1 and 3 of the drawings.

The angle member 58 may be one of four such members forming the supporting frame for the pump, meter, counter and other internal mechanism of the dispensing apparatus. The pivot pin 6B passing through the angle member 58 serves as a pivoted support for the locking pin lever 62. As best shown in Figure 3, this lever 62 is U-shaped in cross section and has a laterally extending actuating arm 64 from which extends a finger piece and latch member 66. The lower portion of the lever 62 engages the outer face of the enlarged head 54 of pin 35, as clearly shown in Figure 1. A projection 6B formed on the lower portion of member 62 engages the angle member 58 to limit the counterclockwise movement of the lever under the inuence of the locking pin spring 56 so that the pin is retained in position in the boss 52 in the nozzle receptacle I3. Y

It will be noted from Figures 2 and 3 that the lever 62 has a limited sliding movement on the pivot pin 60, this movement being at right angles to the movement of pin 34. The lock is placed in locking position by moving the finger piece Y 66 downwardly and sliding the lever 62 to the left on pin 60, as seen in Figure 2, until the upper edge of nger piece 66 ts under the shoulder 10 with the lever in the broken line position of Figure 1. In this position the locking pin 34 will be forced inwardly of the housing i3 and through the perforation 32 in the nozzle hook 21. In this position the locking pin 34 will also be within the guard 23 of the nozzle so that it is impossible to lift the nozzle or pull it out suiciently to clear the housing i3. The upper part of the nozzle I9 cannot be swung outwardly since it is held in the pocket Il. As shown in Figure 1, the lower portion of the guard member 23 is divided to t over the hook 21 as it is moved Y back against the nozzle lever 36.

As shown in Figure 3, the housing H is provided with a door 12 which may be supported at its opposite edge on a hinge which has not been shown. This door 12 carries the lock 'Ui having a locking lug 16 adapted to engage behind the edge of the housing member Il when the housing is locked. The operatingY lever 62 and its finger piece 66 are completely enclosed within the housing and cannot be operated to unlock the nozzle until the door 'I2 is unlocked and opened. Consequently, it is impossible for the lock to be released except by an authorized per- 4 son having a key to the housing. This is accomplished without the use of an additional lock and the locking mechanism is concealed and enclosed.

While I have shown certain preferred embodiments of my invention, these are to be understood to be illustrative only as it is capable of variation to iit diierent structures and to meet differing conditions and requirements, I therefore contemplate such modifications as come within the spirit and scope of the appended claim.

I claim:

A nozzle lock for dispensing apparatus comprising a housing having a recessed nozzle receptacle, a nozzle hook Within the receptacle and a nozzle having a valve lever guard frame tting adjacent the nozzle hook, the nozzle hook and a lateralyvall of the nozzle receptacle being formed with aligned openings, the opening in the nozzle lock being within the nozzle guard frame when the nozzle is seated in the receptacle, a lock pin having an end normally Within the receptacle wall opening, the pin extending outwardly of the receptacle within the housing, a spring normally urging the lock pin away from the receptacle, a pivoted lock pin actuating lever Within the housing, said lever engaging the pin, a stop for limiting movement of the lever to hold the end of the pin in the receptacle wall opening, the lever having an arm for moving the lever to force the lock pin into the receptacle housing and into the nozzle hook opening to lock the nozzle against removal, and means engaging the lever arm for holding the lock pin in locked position.
